'STOVE.

SPECIFICATION forming part of Letters Patent No. 449,929, dated April 7,1891.

Application filed February 21 1890. Serial No. 341,300. (No model.) I

To all whom it may concern:

Be it known that I, EDWARD B. COLBY, a citizen of the United States,residingat Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Stoves; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to whichitappertains to make and use the same.

This invention relates, generally, to stoves, and particularly to thatclass of heatingstoves known as cylinder or sheet-metal stoves; and ithas for its object to provide a simple, durable, and cleanly stovehaving a grate in two parts, both of which may be oscillated in ahorizontal plane at the same time and by the same means, and one ofwhich maybe dumped or tipped over without movingthe other, and inproviding a rest for said grates which may or may not form an integralpart of the base of the stove; and it consists of the parts andcombinations of parts hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a plan view of the grate and base of my improved stove; Fig.2, a vertical section of the same on the line a; m, Fig. 1; Fig. 3, aperspective View of the grate removed from the stove; Fig. 4:, aplanview of the bottom of the gratesupporting ring; Fig. 5, a plan view ofthe top of the base proper; and Figs. 6 and 7 detail sectional viewstaken, respectively, on the lines y yand an m, Fig. 1.

Similar letters refer to similar parts throughout the several views.

A represents the cast-metal base of a stove, to which the sheet-metalbody of the stove is to be secured. The base may be cast in one piecehaving a vertical annular projection a formed at its top and extendingentirely round said base, with the exception of a short spaceimmediately at the front thereof, with a suitable number of perforatedlugs or ears I) projecting therefrom at equal distances apart. The lowerpart of the sheet-metal body of the stove surrounds the annularprojection a and is secured thereto by rivets or screw-bolts and nuts,as is customary, said rivets or screw-bolts passing through thesheet-metal body and through the perforated ears or lugs 19. From theinner side of the annular project-ion a,,at the base thereof, a narrowshelf or ledge 0 projects at right angles entirely round the base, andfrom the edge of this shelf or ledge a narrow annular flange 01 extendsdownward, on the lower edge of which the ears or lugs e are cast, andfrom which they extend at right angles at suitable distances apart toform a firm support for and to permit of the free movement thereon in ahorizontal plane of the grate-sections when the same are shaken. Theears or lugs e are cast of a length sufficient to afford a bearing forthe grate-sections to the full extent of their oscillation, which islimited by the length of the slotf, formed in the side of the base.Outside of and surrounding the annular projection 01,, I form in theupper surface of the base a groove or duct g, the purpose of which is tocatch the dust and finer ashes which sift or work their way between theinner face of the sheet-metal body and the outer face of the verticalannular projection a, and thus prevent the dust and ashes reaching thefloor of the apartment containing the stove. I obviate the annoyanceoccasioned by escape of the dust and ashes onto the floor and carpets,and am enabled to form the body and base separately, and provide asimple, durable, and inexpensive connection between the two andpractically securing the same advantage as a dust-tight connection wouldafford were such practicable in this class of stoves.

The whole of the base just described is cast in one piece; but I may, ifdesired, and it may be preferred so to do, cast the base and the upperpart thereof, which sustains the body, or to which body is directlysecured, separately and secure them together by screwbolts. In order toaccomplish this, I cast the top of the base proper with a flat uppersurface h, from the inner edge of which project at regular intervals thesupporting-lugs 1,having the V-shaped recesses therein, as shown clearlyin Fig. 5. The upper part of the base, which may be termed a ring In, asshown in bottom plan View in Fig. 4, is formed with a dust groove orduct g, an upwardly-extending annular projection 61., theinwardly-projecting shelf 0, downwardly-projecting flange d, and

supporting-ears or lugs a, similar to those do- By this simple meansscribed in connection with the base, and in addition thereto I form orcast thelugs Z (see Figs. 4 and 6) onto the rear surface of the flange(Z, which are adapted when the ring is placed on the base to enterbeneath the lugs or ears t, in order to lock the parts together andprevent the ring and the upper part or body of the stove from topplingover. These parts are also secured together by screw-bolts m, (see Fig.7,) passing through countersunk openings n, formed in the shelf 0 of thering and entering the V-shaped recesses j, formed in the lugs 11, wherethey are secured by nuts 0. By this construction I am enabled to castthe parts separately and then join them together in rigid manner atlittle expense, and rendering it possible at small expense to substitutea new part for a broken part should it become necessary.

The grate is composed of two sections, the outer of which, forming theside walls, consists of ring 1), from the outer edge of which all aroundits circumference, except for a short space immediately at the frontthereof, where said ring is recessed, as at 10', project the horizontalshort bars q, and from the center of the rear side of the ring extends along bar 4", and from each side near the front long bars 7'' are cast,as clearly shown in Figs. 1 and 3, and from the bottom or lower side ofthe ring 13 the bars 3 extend downward in an inclined direction to forma basket-shaped grate. At the rear side of the ring 19, directlyopposite the recess or downwardly-extending offset 19 formed therein,twobars q are cast, which extend below the plane of the bars .9 and havecast on their lower ends the plates 5', 011 which rests one side of theinner or central grate-section B, and also directly opposite each otherat the sides of the ring 19,1 cast the depending lugs forming thehangers t 25, which project in a line parallel with the bars .9, butextend below the plane of the same. The outer grate-section, as thusconstructed, leaves a clear but narrow space between the ends of itsbars q and the inner face of the flange d of the base or ring 70,through which ashes and small cinders may escape when the grate isshaken, and leaves also a central open bottom. It will be observed thatthe bars 8, forming what is termed herein the walls of the grate, arenot joined or connected at their lower ends in any way, but project fromthe ring 19, similar to teeth. For thecentral openingor bottom of theouter grate-section I provide a grate-section B, which is formed of aring 0, having cast therewith the radial bars D, which extend from theouter circumference of the ring and are unconnected at their outer ends,and the bars E extending from the inner side of the ring alsounconnected at their ends. The bars D are of such length as not to reachthe bars 8; but a narrow space is left between the ends of the same allround the bottom of the grate, and said inner grate B is hung with itsupper surface on a plane with the ends of the bars 8. The handle F, bywhich the grate is shaken, and which also supports one side of the innergrate-section, is cast with the mner grate -section and extendstherefrom through the guard-plate G and the slot f formed in the side ofthe base, said handle resting on the hanger t and prevented ,from beingpushed outward by the stops it t1 the former impinging against the innerside of the hanger t and the latter against the guardplate, and servingto hold the same in place while the opposite side of the centralgratesection is supported by the short trunn1on v resting in the hangert at that slde of the outer grate, and being held in place by astop 12formed thereon. The outer grate-section is supported from the base orring through its bars a" and r resting' on the lugs or ears 6. The endsof these bars are adapted to fit accurately against the flange d,thereby preventing the grate from being moved out of alignment andprecipitated into the ash-pan and insuring its true and easy movementwhile being shaken. The length of the slot f in the base is such as tolimit the movement of the grate in either direction to about onehalf thelength of the ears or lugs, so that the bars 0" and 4" cannot be pushedoff the ends of said ears or lugs during the operation of shaking thegrate. The handle F is moved in a horizontal direction back and forth inthe slot f as is customary to shake the grate, said 'forming slotstherein between the bars and having the ends of the bars, both outer andinner, connected.

The inner grate-section may be tipped or dumped to empty the ashes andcinders by giving the handle F a half turn toward the front of thestove, thereby dumping the ashes at the most convenient point forremoval.

The advantage of a grate having a tipping or dumping center or innergrate-section and a non-dumping outer grate-section surrounding the sameover the ordinary grate, the whole of which must be tipped or dumped toempty the stove of ashes, is that there is no liability in shaking thegrate-sections to tip them over, as one of them, as far as any liabilityto tippi-ng over is concerned, is practically rigid and immovable. Alsoby arranging the bars of the grate on the peripheries of the rings theyact as cleaners to knock or agitate the coals and cinders and thusfaci1itate the downward passage of the ashes. Both the upper and lowersurfaces of the central grate-section are made fiat or without curve ofany sort, thereby preventing the ac cumulation of hot ashes thereon,which are liable to warp the same.

Having thus described my invention, what grate-section having the shorthorizontal bars I claim as new, and desire to secure by Letters Patent,is-

1. In a grate, the combination, with the outer grate-section having thehorizontal bars cast on its periphery and the inclineddownwardly-projecting bars, of the center or inner grate-section havingthe horizontal bars cast on its periphery, the inwardly-proj ectinghorizontal bars, and means for supporting said inner grate from theouter grate, substantially as described.
